Mineral Group: [ Wurtzite (20)] ‘Fine specimens of wurtzite, stannite, bismuthinite, and franckeite are relatively common at Llallagua.’ Origin Mid 19th century from the name of Charles A. Wurtz (1817–84), French chemist, + -ite .

Wurtzite has a hexagonal closest packing structure (hcp), which is characterized by 12 ions in the corners of each unit that create a hexagonal prism (seen in Fig. 3). 2 As discussed previously, zincblende slowly transforms to wurtzite due to thermodynamic stability.

For wurtzite, there are four atoms per unit cell in contrast to two for zinc-blende. Since the volume per atom is the same, a given volume of reciprocal space for wurtzite contains approximately twice as many reciprocal lattice points.

Wurtz was a laboratory assistant for Jean Baptiste Dumas at the École de Médecine and succeeded Wurtzite is a rare, high temperature polymorph of the common mineral Sphalerite. It forms at temperatures above 2192º F (1200º C) as hexagonal crystals. An ornamental stone known as Schalenblende (an intergrowth of Wurtzite, Sphalerite, and often Galena) is usually referenced with Wurtzite but is more often listed as a variety of Sphalerite.

Wurtzite zinc oxide (ZnO) is a remarkable multifunctional material with a distinctive property set and a huge range of existing and emerging applications (Look 2006).In particular, it is a direct wide bandgap semiconductor (E g ∼3.4 eV) with intrinsically high transparency over the whole visible range (Fig. 1) and a resistivity that can be tuned from semi-insulating right through to
We have obtained an ordinary/extraordinary average value $\overline{r}$ of 0.49(15) for ZnO, 1.22(9) for GaN, and 0.32(4) for AlN. With the values for the ordinary and extraordinary case being within experimental uncertainty, there is thus no apparent change in dielectric anisotropy under pressure for these wurtzite semiconductors.
